What is the quantity of heat required to raise a unit mass of homogeneous material 1 K in a specified way given constant pressure and volume?

The quantity of heat required to raise a unit mass of a homogeneous material by 1 K at constant pressure is called the specific heat capacity at constant pressure (Cp), while at constant volume, it is referred to as the specific heat capacity at constant volume (Cv). The relationship between these two can be described by the equation Cp = Cv + R for ideal gases, where R is the gas constant. The specific heat values depend on the material's properties and the conditions under which the heating occurs.
